dimeric softball chiral although the monomer itself is achiral. The dimers represent capsules with dissymmetric cavities with volumes ranging from 190 to 390 A(3). The cavities are distorted spheres, and asymmetric guests, such as naturally occurring terpenes, generally prefer one enantiomer of the capsule to its mirror image. The selectivities are moderate (up to 4:1). The complexation studies show that
对垒球的不同同源物进行了研究,以探索对映选择性封装的结构变体。尽管单体本身是非手性的,但单体亚基中的两个不同的间隔元件使二聚垒球具有手性。二聚体代表具有不对称腔的胶囊,体积范围为 190 到 390 A(3)。空腔是扭曲的球体,不对称的客体,如天然存在的萜烯,通常更喜欢胶囊的一种对映异构体而不是它的镜像。选择性适中(高达 4:1)。络合研究表明,宿主胶囊足够灵活,可以在客体周围舒适地安排自己,但仍保持足够的刚度,以受到手性客体占用的影响。
